On Wednesday, Reuters/Ipsos released a rolling poll of hundreds of people that found stable support for federal funding of Planned Parenthood. Between Aug. 13 and Aug. 18, about 54 percent of Americans consistently said they support taxpayer funding for the reproductive health and abortion group. Federal funds are not permitted to be used for abortions except in cases of rape, incest or endangerment of the life of the mother.

But when pollsters changed their question and asked a smaller sample of people for their views on “current efforts” to defund Planned Parenthood, the rolling poll showed a shift: Those who agreed that Planned Parenthood should be defunded grew to 39 percent, while those opposing defunding shrank to 34 percent; another 27 percent said they didn’t know.

The Reuters/Ipsos poll further asked people if the undercover videos had affected their views on Planned Parenthood or abortion. The rolling poll found that 45 percent of people said the videos made them “more negative” about Planned Parenthood, while 33 percent said it hadn’t changed their views, 19 percent said it made them “more positive,” and 3 percent said they didn’t know.
